Hey, it's Outlook (not a bug, but a feature)!
Try another email server to see if that works and to thus narrow down what's going on.
HOPE THIS HELPS.
Okey. Am going to send via outlook, and cant select another email server when sending via a email client. The email client (outlook) opens correctly with the recipiant, and after some second the error message show, the I cant do anything in filemaker or in outlook before I kill Outlook prosseses. Then filemaker shows error that cant send email, and a continue script button. How could I prevent this error ?
First off, to send things out of FM to Outlock you need to install right FileMaker Pro. If you runt Microsoft Office on 32 bit you have to installed FMP on 32 bit. If Office is installed on 64-bit you have to install FMP on 64 bit.
What your Outlock is saying is that you have not given Outlock permission to receive new emails from FileMaker Pro. That is a security issue
